我正在编写类似聊天应用程序的东西,它在我的“公共”文件夹中的DropBox上的.txt文件中写入和读取。我想知道我究竟能做到这一点。
到目前为止我的代码是:
#include <iostream>
#include <fstream>
#include <Windows.h>
#include <cstdlib>
using namespace std;
int main () {
string output;
string outputty;
string Chat;
string option;
string line;
ofstream players;
ifstream chat;
fstream chatw;
cout << "(1) - Enter\n";
cin >> option;
if (option == "1") {
players.open ("C:/Users/Pebsie/Dropbox/Public/data.txt");
string name;
cout << "\nWhat is your name?\n";
cin >> name;
players << name;
players.close();
cout << "Entering..";
chatw.open ("C:/Users/Pebsie/Dropbox/Public/chat.txt", fstream::out | fstream::app | fstream::ate);
chatw << "***" << name << " Entered the game*** " << endl;
chatw.close();
while (1) {
system("cls");
ifstream myfile ("C:/Users/Pebsie/Dropbox/Public/chat.txt");
if (myfile.is_open()) {
while ( myfile.good() )
{
getline (myfile,line);
cout << line << endl;
}
myfile.close();
}
cin >> option;
if (option == "/refresh") {
//DO NOTHING
}
else if (option == "/clearchat") {
chatw.open ("C:/Users/Pebsie/Dropbox/Public/chat.txt", fstream::out);
chatw << name << " cleared the chat." << endl;
chatw.close();
}
else {
chatw.open ("C:/Users/Pebsie/Dropbox/Public/chat.txt", fstream::out | fstream::app | fstream::ate);
chatw << name << ": " << option << endl;
chatw.close();
}
}
system("pause");
chatw.open ("C:/Users/Pebsie/Dropbox/Public/chat.txt", fstream::out | fstream::app | fstream::ate);
chatw << "***" << name << " Left the game..*** " << endl;
chatw.close();
return 0;
}
}
当我编写代码时,我在本地测试它,但仍然写入它,以便用户可以看到我正在更新它。
所以,非常感谢任何帮助,谢谢!
编辑 - 我的问题是,我实际上是如何写入和读取Dropbox文件的。它的公开网址是http://dl.dropbox.com/u/17570838/chat.txt /我如何从在线网址加载文件。
P.S它将被用作测试的聊天应用程序,它显然不是很好,因为它不会自动更新。
